EOS Rebel XT will not connect to Mac after system update

I recently updated my Macbook, so my software is now MacOS Sierra Version 10.12.3. Before this I had no problems connecting my camera to iPhoto. However, with the updated iPhoto is gone and now I just have "Photos". My camera does not show up at all in "Photos".

I go to image capture and it does show up on the left side of the screen but the pictures do not appear and there is no option to click on anything.

I have gone to "Applications" -> "Utilties" -> "System Information" and the camera does appear there under "USB" so the computer is reconizing it to some point but won't do anything.

When I open the Canon software that I just updated (Camera Window DC 8), it says no camera found.

HELP PLEASE!! I have tried a different USB cord. I have tried a different CF card. I have contacted Apple and they had me try a few things but nothing helped.

Thanks so much for reading and I hope someone has a solution! Thanks!!
